[Openswan Users] Ipsec error : no connection is known

[Frédéric Gonzatti]

Hello Nate,

I've tried to open the new 4500/udp port from my router to the ipsec0 
interface but unfortunately I can't ping  a LAN computer from my XP client.
When I enter ipsec barf on my ipsec gateway I've got the following 
messages :
packet from 80.170.210.44:500 : ignoring Vendor ID payload ....
"roadwarrior"[1] 80.170.210.44 #1 Peer ID is ID_DER8ASN1_DN :'C=FR .....'

roadwarrior"[2] 80.170.210.44 #1 : deleting connection "roadwarrior-net" 
instance with peer 80.170.210.44
.....

When I'm trying to ping a LAN computer from my XP, the first two times I 
have a message "Negociating security...." and afer a long moment a delay 
error message.
NB : The error : no connection is known is not present.

Thanks again for your precious help.
